Welcome to
What is

InspIRCd is a modular Internet Relay Chat (IRC) server written in C++ for Linux, BSD, Windows and macOS systems.

It was created from scratch to be stable, modern and lightweight. It provides a tunable number of features through the use of an advanced but well documented module system. By keeping core functionality to a minimum we hope to increase the stability, security and speed of InspIRCd while also making it customisable to the needs of many different users.

And after all it’s free and open source.
